Why is z-index not working on my elements?
I have my code set up so I have a hero image at the bottom and on top at the top with text and a button in the overlay. I also have a z-index navbar, but for some reason the button for my resume in the overlay is not working.
Html
<div id="header">
<a href="index.html"><div id="leftHeader">
<img src="assets/logo2.jpg" alt="Logo" style="width:65px;height:65px">
<h1>Amanda Farrington</h1>
</div>
<div id="nav">
<ul>
<li><a href="about.html">About</a></li>
<li><a href="#workJump">Work</a></li>
<li><a href="contact.html">Contact</a></li>
<li><a href="notes.html">Notes</a></li>
</ul>
</div>
</div>
<div id="hero">
<div id="heroImage">
<img src="assets/trees.jpg" alt="trees" style="width:100%;height:10%">
</div>
<div id="overlay">
<h2>Amanda Farrington</h2>
<h3>Graphic Artist | Web Designer</h3>
<a href="assets/resume.pdf" class="down">View Resume</a>
</div>
</div>

So, I took a look at your code and the reason your button is not working is because the div with the #hero id (which contains the button) is below the body as it has a z-index of -1.
Set the z-index for #hero to 0 or higher and the button will work.
#hero {
padding-top: 25em;
width: 100%;
height: 30em;
position: relative;
z-index: 0;
}
Check out this JS Fiddle I created for you: https://jsfiddle.net/8fqwr6ca/
Edit: Oh, and I forgot to mention - since you want the image below, set #hero z-index to 1, set #heroImage to 0 and overlay to 2. This should do the trick (if I think you want right).
